ready they look like large spiky balls that would be impossible to swallow. unlike the puffer fish, a hedgehog curls itself up into a prickly ball when it senses danger. its sharp spines will poke the tender nose of anything that tries to eat the hedgehog. the pangolin is covered in hard, scaly plates that are like a suit of armor. when threatened, it also rolls itself up into a bite - proof ball. puffer fish, hedgehogs, and pangolins all have outer defenses. fill in the blanks to compare and contrast puffer fish, hedgehogs, and pangolins. puffer fish, hedgehogs, and pangolins are similar because they all defend themselves with protective parts. they are different fer fish defend themselves, while and pangolins themselves into a ball. (options: extra, inside, outside)

Question

Accepted Answer

# Brief Explanations:
1. For the first blank (describing the protective parts' location), puffer fish, hedgehogs, and pangolins have protective parts on the outside (spines for puffer fish and hedgehog, scaly plates for pangolin), so "outside" fits.
2. For the second part about puffer fish's defense: The text says puffer fish "look like large spiky balls that would be impossible to swallow" (implying they puff up, but the key difference from hedgehog and pangolin is that hedgehog and pangolin curl into a ball, while puffer fish's defense is more about puffing (but the blank structure: "Puffer fish defend themselves ____, while hedgehogs and pangolins ____ themselves into a ball." Wait, re - reading the right - hand text: "They are different Puffer fish defend themselves ____, while ____ and pangolins ____ themselves into a ball." Wait, the original right - hand text: "They are different Puffer fish defend themselves [first blank], while [hedgehogs] and pangolins [second blank] themselves into a ball." From the left text: Hedgehog "curls itself up...", pangolin "rolls itself up...". Puffer fish's defense: the text says "they look like large spiky balls that would be impossible to swallow" (so maybe "by puffing up" but the blank options? Wait, the first dropdown has "extra", "inside", "outside" – no, wait, the first blank in the right - hand text: "Puffer fish, hedgehogs, and pangolins are similar because they all defend themselves with protective [blank] parts." So the first blank (the dropdown) is for the location of protective parts. Since their spines (puffer, hedgehog) and scaly plates (pangolin) are on the outside, the first blank is "outside". Then the next part: "They are different Puffer fish defend themselves [how?], while hedgehogs and pangolins [verb] themselves into a ball." From the left text: Hedgehog "curls itself up", pangolin "rolls itself up". Puffer fish's defense: the text says "they look like large spiky balls that would be impossible to swallow" (so maybe the way they defend is different from curling/rolling into a ball. Wait, the original right - hand text: "They are different Puffer fish defend themselves ____, while ____ and pangolins ____ themselves into a ball." Wait, the user's image: the right - hand text has a dropdown for the first blank (with "extra", "inside", "outside"), then "Puffer fish defend themselves [first blank], while [hedgehogs] and pangolins [second blank] themselves into a ball." So first blank: protective parts are outside (so "outside"). Then, hedgehogs and pangolins curl/roll into a ball, so the second blank (the verb for hedgehogs and pangolins) – from the left text, hedgehog "curls itself up", pangolin "rolls itself up" – but the blank is for the verb. Wait, maybe the first blank (the dropdown) is "outside" (protective parts are outside). Then, "Puffer fish defend themselves [by puffing? No, the options? Wait, no, the first dropdown is for the first blank in "protective [blank] parts" – so "outside" (since their spines and plates are on the outside). Then, "Puffer fish defend themselves [in a way different from curling/rolling], while hedgehogs and pangolins [curl/roll] themselves into a ball." So putting it all together:

First blank (protective parts location): "outside" (because their spines and plates are external).

Then, "Puffer fish defend themselves [without curling/rolling, just puffing], while hedgehogs and pangolins [curl/roll] themselves into a ball." But from the left text, hedgehog "curls itself up", pangolin "rolls itself up" – but the blank is for the verb. However, the main blanks to fill (from the image's right - hand side):

The first dropdown (for "protective [blank] parts"): "outside" (since puffer fish has spines outside, hedgehog spines outside, pangolin plates outside).

Then, the next part: "They are different Puffer fish defend themselves ____, while ____ and pangolins ____ themselves into a ball." Wait, maybe the first blank (after "defend themselves") is "by puffing" but no, the dropdown options? Wait, no, the first dropdown is for the "protective [blank] parts" – so "outside". Then, the other blanks: "Puffer fish defend themselves [in a way not curling], while hedgehogs and pangolins [curl] themselves into a ball." But the key is to fill the blanks as per the text.

So, step - by - step:

1. First blank (protective parts location): The protective parts (spines, scaly plates) are on the outside of their bodies. So the first dropdown (with "extra", "inside", "outside") should be "outside".

2. Then, "Puffer fish defend themselves [differently from curling/rolling], while hedgehogs and pangolins [curl/roll] themselves into a ball." From the left text, hedgehog "curls itself up", pangolin "rolls itself up" – but the blank is for the verb. However, the main blanks to fill (the ones with dropdowns) are:

- The first dropdown (protective parts location): "outside"

- Then, for the part "Puffer fish defend themselves ____, while ____ and pangolins ____ themselves into a ball." The second blank (the animal) is "hedgehogs", and the third blank (the verb) – from the text, hedgehog "curls", pangolin "rolls" – but maybe the answer expects "curl" or "roll". But looking at the left text: Hedgehog "curls itself up", pangolin "rolls itself up" – but the blank is for the verb that hedgehogs and pangolins do to themselves into a ball. So "curl" (for hedgehog) and "roll" (for pangolin), but the blank is a single verb? Wait, maybe the text's structure is that hedgehogs and pangolins "curl" or "roll" themselves into a ball. From the left text, hedgehog "curls itself up", pangolin "rolls itself up" – but the blank is a verb that both do? No, maybe the answer is:

First blank (protective parts location): "outside"

Then, "Puffer fish defend themselves [by puffing] (but no dropdown for that), wait, no – the user's image shows a dropdown for the first blank (with "extra", "inside", "outside") – that's the first blank. Then, the next part: "Puffer fish defend themselves ____, while ____ and pangolins ____ themselves into a ball." The "____" after "defend themselves" – maybe the way they defend is different from curling into a ball. But from the text, hedgehog and pangolin curl/roll into a ball, while puffer fish's defense is being a spiky ball (maybe by puffing, but the key is the blanks.

So, to fill the blanks:

1. The first blank (protective parts location): "outside" (because their spines and plates are external).

2. Then, "Puffer fish defend themselves [without curling/rolling], while hedgehogs and pangolins [curl/roll] themselves into a ball." But the main blanks with dropdowns:

- First dropdown (protective parts location): "outside"

- Then, for the verb (hedgehogs and pangolins): from the text, hedgehog "curls itself up", pangolin "rolls itself up" – but the blank is a verb. However, the most appropriate verb for both (or the one that fits the structure) is "curl" (for hedgehog) and "roll" (for pangolin), but since the blank is for what hedgehogs and pangolins do to themselves into a ball, the answer is that hedgehogs and pangolins "curl" (or "roll") themselves into a ball, and puffer fish defend themselves in a different way (but the first blank is "outside").

So the filled blanks would be:

"Puffer fish, hedgehogs, and pangolins are similar because they all defend themselves with protective outside parts. They are different Puffer fish defend themselves [in their own way, e.g., by puffing], while hedgehogs and pangolins curl (or roll) themselves into a ball." But based on the dropdown options, the first blank is "outside".

# Answer:
- First blank (protective parts location): outside
- For the part "while ____ and pangolins ____ themselves into a ball": hedgehogs; curl (or roll, but "curl" is more accurate for hedgehog, "roll" for pangolin. However, from the text, hedgehog "curls itself up", so "curl" is a good choice for hedgehogs, and pangolins "roll" – but if we have to choose one verb, maybe "curl" as hedgehog is mentioned first)
